ROTARY PUMP.

Specification of Letters Patent.

' Patented. June 9, 1908.

Application filed July 12, 1906. Serial No. 325,80

To all whom it may concern:

Be it known that we, MAURICE MOORE and J OHN MURRAY, subjects of theKing of Great Britain and Ireland, and residents of 178 Bellair street,Kensington, in the city of Melbourne, in the county of Bourke, and 118 Uper H0 e street,'in the town of Geelong est, in t e county of-Grant,respectively, both in the State of Victoria and Commonwealth of-Australia, have invented certain new and useful Improvements in RotaryPumps, of which the following is a specification. I

The object of our invention is to provide a mechanism for pumping air,gas, water or liquids or semi liquids of any character. In the past avariety of devices have been used to t and simple pump is produced havinbut few wearing parts and absorbing but little ower. Referring to thedrawings which orm a part of this specification Figure 1 is an elevationpartly in section of our pump. The

, driving tongue being at the top. Fig. 2

cover an the casing and the pumping disk occupy the is a view of thedischarge end of our casing andpum ing disk. The bracket discharge thering are removed and both same relative position t at they do in Fig. 1.Portion of the pumping disk is broken away to show the passa e-ways fromthe ports to the tubular spind es. Fig. 3 is an interior view of part ofthe casing, andis similar to Fig. 2 except that the pumping disk,driving tongue and suction ring are removed. Fig.

- 4 is a plan of the pumping disk showing the suction and dischargeports and the outer end, of the driving tongue between them.

mg hole E.

Figf5 is a plan on a. reduced scale of the suction ends of two pumpswhen placed together.

Similar letters of reference. indicate'similar or corresponding partswhere they occur in the several views.

Our invention includes a base plate A above each end of which upstands abracket.

Oneof these is called the suction bracket B and the other the dischargebracket O. Protruding horizontally from the inside of each bracket andnear the to of the same is a boss D. Through eachv oss and eccentricwiththe same is an eccentric spindle bear- Protrudin from the outside andnear the top of each racket and concentric with the is end, but with ourinvention a cheap spindle bearing hole before referred to is a stuflingbox F. In this is a gland G or in lieu of there being a gland adjustedby studs and nuts as shown, an internally threaded nut gland may beused. The outer ends of each of the said glands protrude and are eitherthreaded internally or externally to receive connections G Turningaround each boss before referred to is a cover plate. There are thus twocover plates, and the suction one is marked Hand the discharge one J.Each cover plate is prevented from moving outwardly upon the said bossby a shoulder K. It is prevented. from movinginwardly by a leatherWasher L which is secured to the boss D by a holding 7 plate M. Thisholdin plate M is fixed to the said boss by screws N Fi The said leatherWasher L is larger in diameter than the holding plate M and surroundingg. 3) or other means.

the enlarged portionis a looking or jointing ring P. Each one of theserings P, by screws Q or other means, is secured to its cover plate andturnsror rotates with it. The leather washerand the holdin plateeach-have an eccentric hole therethrough ofapproximately the samediameter as the eccentric hole E before referred to. Y

Freely turning in each eccentric spindle bearing hole is a tubularspindle. One of these is hereinafter called thesuction spindle R and theother the discharge spindle S.

The outer end of each spindle passes into the stufling boX F beforereferred to and turns therein. The inner ends of the spindles areconnected to or are integral with a pumping disk T which may becentrally situated between the said two spindles. The width of the saidpumping disk as also its diameter will depend upon conditions. In itscircumference are two ports, the suction port U and the discharge port V(see Figs. 2 and 4). Between the said suction port U and the tubularsuction spindle R is a suction passageway each cover.

, attached a driving ring L "the casing is a ton ue end of this isclosed y a cover plate D this box is a radial passageway E (see Fig.

inafter referred to. Into this combination hole is passed the inner orheaded end A (Fig. 2) of a rectan ular sectioned driving tongue B Thesai driving tongue therefore protrudes radially from the said disk.

Attached between each of the cover plates H and J is the pump casing CHThe interior of this is larger in diameter than the disk and there isexisting between the disk and the interior of the casing acrescent-shaped space (see Fig. 2). Protrudin from the outside of ox DThe outer In 1) to accommodate the outer end of the driving tongue whichton ue moves in and out of the passa eway radially as the casing and thepump dis rotate. v

Inside the casin and at each side of the pumping disk is pTaced a ringF. In each such ring is a central hole F which is larger than the si'ndle to allow of the eccentric travel of t e saidspindle'. At the sideof each ring is'also a chamber-Gr into which escaping water passes. Theinner surface H of each ring F is pressed against the disk side byadjusting screws J passing through Throu h each ring F is a dlschargehole K (see ig. 2.)

To the circumference of the casing may be This may accommodate a fiatleather belt or may be 'provided'with sprockets to accommodate a chain.Or it may be rooved to afford a rope guide. Or it may e toothed drivenor the casing may be wound in such a manner as to form the armature ofan electric the water chamber M motor, in which case it will beelectrically driven.

Two of our pum s may be placed suction end to suction en as seen in Fig.5. The stuffing boxes and the glands G then lead into Into this thesuction water through the inlet hole N enters and passes into thesuction spindles R. The s indles overhang the glands G' as seen.

ound each end is recessed a thrust late 0 The distance between the saidt ust plates is adjusted by means of the adjusting olts P These areprevented from rotating by the stop Q or other means. The said chamberis closed and provided with an inspection cover. V

The cycle of 0 erations with our invention isas follows-T ewater is ledto the suction seas-es connection G on the suction gland and from thereinto the suction spindle R of the pumping disk T. It then passes throughthe suction passageway W outwardly till it reaches the suction port Uwhen it is liberated into the space existing between the circumferenceof thesaid pumping disk T and the inner wall of the casing C As thiscasing rotates the outer end of the driving tongue B drives the inneror-headed end A of the same. This turns the pumping disk T so that thesaid disk and casing C rotate together. The water drawn in through thesuction spindle R as the casing rotates is compressed within the casingand finds exit through the discharge port V in the circumference of thesaid pumping disk T. It then passes inwardly through the dischargepassageway X to the discharge spindle S and then through the connectionG The chambers G in the rings F gather any water that may escape betweenthe inner surface of the said ring and the surface of the disk.Centrifugal force throws this water through the discharge hole K (Fi 2)into the suction space inthe casing. similar action to the foregoingtakes place when'two suction ends are placed together as seen in Fig. 5save that the suction water first enters the water chamber M beforeitenters the suction spindles.

Having now described our invention what we claim as new and desire tosecure by Letters Patent is In a pump, a pair of brackets, each brackethaving a stuffing-box and a gland in each stuffing-box, a boss on theinner side .of each bracket, a shoulder on each boss, a cover plate foreach boss, a leather washer having an enlarged end and retaining saidcover plate in place, a plate securing said washer in place, and. alocking ring surro'unding the enlarged portion of said washer, incombination with a casing rotatably supported bei I tween said brackets,a suction disk rotatable with the casing, tubular suction and dischargespindles connected with said disk, and a driving tongue connected withsaid casing and with said disk.
